healthy, symmetrical, well- shaped, full branched, and well rooted. The plants shall be free

condition, will be rejected by the Landscape Architect, either before or after planting, and

E. Trees shall be healthy, full- branched, well- shaped and shall meet the trunk diameter and
height requirements of the plant schedule. Balls shall be firm, neat, slightly tapered, and
